dc.description.abstract

Motor coordination is an important feature of intra- and
inter-personal interactions, and several scenarios | from _nger tap-
ping to human-computer interfaces | have been investigated experi-
mentally. In the 1980s, Haken, Kelso and Bunz formulated a coupled
nonlinear two-oscillator model, which has been shown to describe many
observed aspects of coordination tasks. We present here a bifurcation
study of this model, where we consider a delay in the coupling. The
delay is shown to have a signi_cant e_ect on the observed dynamics. In
particular, we _nd a much larger degree of bistablility between in-phase
and anti-phase oscillations in the presence of a frequency detuning.
